A summary and discussion of a series of studies considered the dilemma that equal educational treatment of all children in public schools appears likely to increase the spread of differences among them in educational achievement. Longitudinal studies of pairs of identical and of fraternal twins in Sweden from 10 to 18 years of age considered the…

Since the need for good programers exists and will increase, their identification before training is desirable. Until now only single tests of potential ability have been evaluated. In this study several tests used in various combinations were evaluated as test batteries. The IBM Aptitude Test for Programmer Personnel (ATPP) and the Strong…

The selection of an appropriate test battery is based on its content and applicability to the vocational trainee population. This report describes the testing of a national sample of U.S. high school students with an established version of Armed Services Vocational Aptitude Battery (ASVAB), and a new, enlarged version of the same test battery.…

This norms study, initiated to aid in score interpretation, is designed to provide current information on Preliminary Scholastic Aptitude Test/National Merit Scholarship Qualifying Test (PSAT/NMSQT) scores of a national sample of high school juniors. Earlier national norms were developed on the basis of tests administered in 1960 and 1966. The…

The United States Training and Employment Service Aptitude Test Battery (GATB), first published in 1947, has been included in a continuing program of research to validate the tests against success in many different occupations. The GATB consists of 12 tests which measure nine aptitudes: General Learning Ability; Verbal Aptitude; Numerical…

The field-tested activity manual is intended to improve cooperative education coordinators' relationships with their students by providing an individualized approach that allows the student to participate in planning the area of emphasis for study and activity. Although useful in regularly scheduled classes, it was prepared especially for those…

This study investigated the effects of high and low need achievement, individual vs. group test adminstration, and potential dropout and nonpotential dropout on the Manual Dexterity Aptitude of the General Aptitude Test Battery. Following the administration of the Thematic Apperception Test (TAT), 120 high school males were assigned to one of…

This review summarizes the major criticisms of standardized tests and testing and attempts an evaluation of the validity of the criticisms. Viewed in the context of type of test, manner of its use, and assumptions regarding its validity, the paper discusses: (1) the imperfect-prediction problem, where predictions of performance are invalidated by…

Three stages mark the development of relevance in testing: relevance to the educational program, relevance to the individual student's past accomplishments, and relevance to the student's future accomplishments. If the College Entrance Examination Board should have to follow paths such as these, it has ahead of it the enormous job of transforming…

A series of five reports is presented which describes the activities carried out by the Pennsylvania State University group engaged in research in computer-assisted instruction (CAI) in vocational-technical education. The reports cover the period January 1968-June 1968 and deal with: 1) prior knowledge and individualized instruction; 2) numerical…

The purpose of this paper is to report on a pilot investigation of the operation of the Bloom and Carroll hypothesis which states that aptitudes are predictive of rate of learning given a situation in which the time allowed for learning is unlimited, and pupil perserverance, ability to understand instruction, and quality of instruction are…

Information from tests, when considered in the context of decision theory, can play an important role in vocational development. This role is primarily one of stimulating and facilitating exploratory behavior. Objective procedures for converting test data into counseling information are discussed and illustrated with special attention being given…

Do we control tests, or do these instruments of measurement control us? Standard scores, percentiles, norms, standard deviations and other elements of measurement can assist the educative process or degenerate into mechanical crutches. There is general consensus among most educators that learning is a multifactor experience involving, among other…

A nontechnical approach to statistics is presented. The examples and illustrations have been drawn from the classroom and the needs of teachers who wish to measure and understand the progress of their pupils. The areas covered include the following topics: (1) different forms of average, middle value, dispersion of data around the average, and the…

It is now widely agreed that current ability measures reflect a complex interaction of environment with genetic potential. This leads to a basic measurement problem since persons with the same measured ability may vary widely in potential due to non-equivalent learning opportunities. The purpose of this paper is to present a model which may hold…
